9 minutes into the second video on this page gives a good explanation of the method required. Children will have learnt exchanging in class during the week commencing 23/11/20.
Session 2: Children may benefit from drawing a picture in a bid to better understand what is being asked of them. Using columns for both addition and subtraction is the best method to use.
This video is a great way of introducing arrays: visual representations of multiplication sentences.
Session 4: As with Session 3, children further explore the visual representation of multiplication sentences. 'Commutation' is the technical term in maths to explain that 3x5 is the same as 5x3.
Challenge: Children can make their own arrays using beads/counters/dried food at home and write down twp multiplication sentences for each.
